讲座内容：

Lastgeneration of gamma-ray instruments has brought binaries to the forefront ofnon-thermal high energy astrophysics.They are well established gamma-ray sources of high energy (HE, 0.1-100 GeV)and very high energy(VHE, >100 GeV), displaying variability on a timescale related to the binarynature. They provide access to different physical conditions on relativelyshort periodic time scale, which allows access to different conditions forefficient particle acceleration along orbit. The elite sub-groups of binarysystems seen in gamma rays are gamma-ray binaries, microquasars, colliding windbinaries, Novae and binaries containing recycled pulsars. I will give a shortreview of these systems.
